What is the image for 1, -6 for 180° counterclockwise for the rotation about the origin

Need an artist designed a badge for a school club. figure abcd on the coordinate grid below shows the shape of the badge: the badge is enlarged and plotted on the coordinate grid as figure jklm with point j located at (2, -2) and point m is located at (5, 4). which of these could be the coordinates for point l? a. (2, 4) b. (8, 4) c. (5, 1) d. (5, 7)

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

Can someone me with this? i’m not sure what to put for my equations.
